husqvarna vitpilen 401 Top Speed & Performance Review
The cafe racer and modern scrambler styles have surged back into the spotlight in recent years. While some manufacturers simply mimic vintage designs in their new models, Husqvarna took a more innovative approach.
The Vitpilen 401 melds timeless aesthetics from the past with the latest engineering advancements. Shunning the ubiquitous parallel twin platform, Husqvarna opted for an advanced 373cc single-cylinder powerplant. Thoroughly modern, yet wrapped in a stylishly minimalist retro package.
But the Vitpilen aims to deliver more than just showroom appeal or abstraction from the norm. Husqvarna engineered this motorcycle to deliver a uniquely engaging and dynamic riding experience. The focal point of that hands-on performance ethos centers sharply on the bike’s top speed capabilities.
Can Husqvarna’s neo-retro machine finally eclipse that seemingly elusive 100 mph marker? To answer that question, we’ll analyze the Vitpilen’s acceleration, powerplant vitals, gearing, weight reduction measures, aerodynamics and electronic limitations. We’ll also see how various modifications can unleash even greater velocity.
By reviewing both independent testing results and owner experiences, we’ll determine if this svelte Swedish single has enough steam to join triple-digit territory. If any entry-level 400cc machine can accomplish such a feat, the spirited 2023 Vitpilen 401 stands the best chance of surmounting 100 mph. Let’s scrutinize the top speed equation of this mini road racer…

Let’s now scrutinize why this neo-cafe racer struggles to conclusively clear 167 kmph (approximate) when running bone stock.
Vitpilen 401 Acceleration and Power Figures
In the motorcycling world, there is no replacement for displacement. And bigger bikes with two or more cylinders understandably grab all the speed-focused spotlight.
Yet today’s advanced single-cylinder engines extract markedly more power from smaller displacements than ever before. KTM’s DUKE motorcycles reset expectations of thumping thumpers, and Husqvarna adopts that platform for the Vitpilen 401.
Its fuel-injected 373cc powerplant utilizes an oversquare architecture, with an 89mm bore and 60mm stroke. The SOHC four-valve head allows efficient breathing, fed by dual 40mm throttle bodies. Compression ratio is 12.6:1.
While no fire-breather, output specs still impress:
- 32 kW power
- No horsepower and torque figures provided
Translated to the tarmac, that equates to a 0-60 mph sprint time of 3.6 seconds. Helped by the feathery 151 kg curb weight, the Vitpilen boasts a nimble power-to-weight ratio.
So acceleration and general thrust clearly aren’t the limiting factors capping velocity. Where does the bottleneck emerge that prevents joining 167 kmph (approximate) territory?
Why is the Vitpilen 401 Limited to 100 MPH?
While certainly no slug off the line, the Vitpilen 401 eventually runs out of steam shy of higher velocities. Owners cite the factory speed limiter as the proverbial governor, electronically throttling momentum before hitting astronomical revs.
On unrestricted roads or racetracks, other 397-403cc singles can ultimately top higher speeds given enough tarmac. But it requires screaming near redline in top gear for extended periods, placing excessive loads on the powertrain.
For longevity and safety reasons, manufacturers electronically limit highway velocity – often 10-15 mph below realistic peak speeds. At an indicated 167 kmph, the engine RPMs already verge on excessive.
While the Vitpilen 401 harbors ample performance for legal highway cruising, it purposefully falls just shy of higher velocities when stock.
Let’s explore what specific performance modifications can finally help this neo-retro Husqvarna eclipse faster speeds.
How to Make the Vitpilen 401 Faster?
Unlocking the Vitpilen’s ultimate velocity requires addressing three vital areas – aerodynamics, gearing, and electronic restrictions:
Improve Aerodynamic Penetration
The upright riding posture and minimal bodywork that define this motorcycle’s styling also hamper high-speed stability and fuel mileage. A slippery profile cheats the wind more efficiently.
Consider installing:
- Low-profile windscreen
- Bell-moto fairing kit
- Tail tidier/license plate relocator
- Shorty GP exhaust
Adjust Final Drive Gearing
Lower gear ratios hinder acceleration in lower cogs but sacrifice maximum speed. Adjusting the drivetrain can provide benefits:
- Improves torque for faster exits
- Theoretical top speed increase
Just ensure specifications stay within proper range with any gearing changes.
Derestrict Top Speed Limiter
This final step electronically unbridles the leashed acceleration built into the ECU mapping and ABS module. But ample caution warranted!
Safely unlocking performance requires professional Dyno tuning and flashing revised software. Not for novices.
With these modifications completed, the Vitpilen 401 may ultimately surpass higher velocities. But for public road usage, we can’t recommend de-restricting speed limiters. When professionally modified under controlled environments, the Vitpilen shows its performance potential.
Factors That Determine Top Speed
Aside from electronic limitations, what technical elements factor into overall maximum velocity?
Engine Power vs Wind Resistance
Initially, increasing throttle directly translates to greater acceleration. But aerodynamic forces rise exponentially as speeds climb. The motorcycle eventually reaches a balancing point where wind drag equals the rear wheel output.
Upright nakeds like the Vitpilen 401 lack the penetrative profile of fully-faired bikes, hampering terminal velocity despite similar horsepower. Finding the ideal compromise involves balancing riding style, performance expectations and safety.
Gearing
Lower overall gear ratios allow faster acceleration off the line. But fuel efficiency and maximum speed suffer on the highway. The ideal drivetrain compromise balances intended riding style with performance expectations.
Weight Savings
The Vitpilen 401 tips scales at a scant 151 kg wet. Further reductions in mass help acceleration. But at highway speeds, a kilo here or there makes negligible aerodynamic difference.

How Does The Vitpilen 401 Top Speed Compare?
The nimble neo-retro Husqvarna significantly outruns entry-level 250-300cc twins in ultimate pace potential thanks to its advanced thumper powertrain. The 373cc engine easily hexes the Kawasaki Ninja 400 or KTM RC390 in a straight line dash once rolling.
But larger displacement rivals ultimately prevail in top speed bragging rights:
- KTM 390 Duke: 108–113 mph (de-restricted)
- Yamaha MT-03: 108 mph (de-restricted)
- Honda CB500F: 112 mph
- Suzuki SV650: 130 mph
The Vitpilen 401 still holds its own against direct 400cc adversaries, with acceleration and handling that belie its diminutive engine size. Refined ergonomics differ markedly from petite sportbikes, offering comfortable long-distance capability.
Just don’t expect to outraced any 600cc supersports – or even certain 500cc twins – in an unrestricted top speed joust. But protecting your license was never the ethos behind Husqvarna’s Subtle Super Hooligan…
Owner Impressions – Vitpilen 401 Highway Capability
While hard acceleration runs or maximum velocity tests deviate from this bike’s intended realm, many owners still wish to exceed legal speeds now and then. Let’s see what Vitpilen pilots report when riding closer to the limits:
“Even two-up, I hit an indicated 167 kmph on a straight. Felt planted despite the small windscreen, but the engine buzzed up around 9k rpm!”
“For sane highway cruising it’s remarkably smooth. I can ride legal speeds for hours if I stop to stretch.”
“Got trapped trying to pass a truck on a narrow road. Pinning the throttle, saw an indicated 167 kmph before finally squeezing past!”
So while Husqvarna electronically limited top speed, owners praise sharp handling at highway velocities. The compact chrome-moly chassis provides stability when riding. Just expect some engine buzziness exceeding legal speeds.
Pros And Cons Of The Husqvarna Vitpilen 401
